The present study aimed to investigate the effects of aldosterone on vascular endothelial cells and the viability of poly (ADP-ribose) polymerase 1 (PARP1) in cells, and to examine the molecular mechanisms underlying the effects of aldosterone on vascular endothelial cell injury. Cultured endothelial cells were treated either with different concentrations of aldosterone for the same duration or with the same concentrations of aldosterone for different durations, and the levels of apoptosis and activity of PARP1 in the cells were detected, respectively. Aldosterone receptor antagonists or PARP1 inhibitors were added to cells during treatment with aldosterone and the levels of apoptosis and activity of PARP1 were detected. As the concentration of aldosterone increased or the treatment time increased, the number of apoptotic cells and the activity of PARP1 increased. The aldosterone receptor antagonists and PARP1 inhibitors inhibited the increase of apoptosis and PARP1 activity caused by aldosterone treatment. Aldosterone activated the activity of PARP1 via the aldosterone receptor, inhibiting cell proliferation and inducing apoptosis. Treatment with PARP1 may be used as a target for vascular diseases caused by aldosterone at high concentrations.
